Abstract

The utility model relates to a nebulizer special for mechanical ventilation. Due to the facts that nebulized particles generated by an ultrasonic nebulizer are large and the nebulization speed is high, a patient inhales too much vapor, the respiratory tract is humidified, part of original dry and thick secreta, blocking the bronchi, inside the respiratory tract will expand after absorbing water, the resistance of the respiratory tract is increased, the phenomenon of oxygen deficit may occur; besides, the ultrasonic nebulizer enables liquid medicine to form water drops and be hung at the wall of a lumen, the treatment effect for lower respiratory tract diseases is poor, a large amount of medicine is needed, and waste is caused. The nebulizer special for mechanical ventilation comprises a liquid medicine chamber (1), wherein the liquid medicine chamber is connected with an aerial fog generator (4), the aerial fog generator is connected with a nebulization medicine chamber (2), and the aerial fog generator is connected with a frequency controller. The nebulizer special for mechanical ventilation is used for nebulization of liquid medicine.

Description

The special-purpose nebulizer of mechanical ventilation
technical field:
this utility model relates to the special-purpose nebulizer of a kind of mechanical ventilation.
background technology:
medical vaporizer is mainly used in treating various upper and lower respiratory system diseases, as the disease being occurred in trachea, bronchus, alveolar, the thoracic cavities such as flu, heating, cough, asthma, laryngopharynx swelling and pain, pharyngitis, rhinitis, bronchitis, pneumoconiosis.Atomization inspiration treatment is a kind of important and effective Therapeutic Method in respiratory system disease Therapeutic Method, adopt nebulizer that medical liquid atomizing is become to molecule, the mode that medicine sucks by breathing enters respiratory tract and pulmonary deposition, thereby reaches object painless, that effectively treat rapidly.Existing nebulizer is mainly ultrasound atomizer.
the aerosol apparatus of ultrasound atomizer is to droplet non-selectivity, so the drug particles major part producing only can be deposited on the upper respiratory tract such as oral cavity, throat, and due to the deposition of pulmonary seldom, can not effectively treat lower respiratory illness.Simultaneously, the droplet producing due to soniclizer is large, and atomization is fast, causes patient to suck too much steam, make respiratory tract humidifying, after the bronchial dry thick secretions of original Partial Blocking absorbs moisture in respiratory tract, expand, strengthen airway resistance, may produce anoxia phenomenon, and soniclizer can make medicinal liquid form the globule to hang on internal chamber wall, to lower respiratory illness poor effect, large to pharmaceutical requirements amount, wasting phenomenon.
